Suggestion for Custom Type-Ins

So we already know custom type ins are a thing and there are also default auto type ins too. I was wondering if there was a way to combine the two features in a simplification process for custom type ins where maybe we can have our own personal data banks to apply custom type ins to answers we frequently use that do not have default type-ins. Let me know if you get the idea I'm saying here cause I have no idea if I articulated that correctly.
